Model-specific archive record. Enclosure labels do not always identify the installed mechanism or host controller; preserve the full suffix and inspect the unit before connection or service.
MODEL IDENTIFICATION: Apple M0130. Photograph the nameplate, serial, connector and power rating. Verify revision-specific instructions and inspect any replacement mechanism before use.
Recorded specifications
| Exact model | Apple M0130 |
|---|---|
| Drive size / type | 3.5-inch external floppy drive. |
| Capacity / formats | 400 KB Macintosh GCR, single-sided; not IBM 360 KB FAT media despite similar nominal capacity. |
| Interface / controller | Apple Macintosh external floppy interface via proprietary 19-pin drive connector and compatible host controller. |
| Power | Host supplied through the supported external-drive connection; use the correct Apple cable/host and inspect modifications. |
| Host OS / system compatibility | Original Macintosh 128K/512K-era systems that support an additional 400 KB drive; later compatibility depends on ROM and drive control. |
| Cable / connectors | Apple DB-19-to-DB-19 external-drive cable; not interchangeable with PC serial/parallel cables. Avoid hot-plugging. |
Compatibility and preservation caveats
400 KB GCR media is not directly interchangeable with 800 KB Macintosh or PC MFM formats. Inspect eject, head and replacement mechanism.
Inspect for corrosion, contamination, cracked plastics, damaged shutter, cable strain and prior repairs. Do not insert damaged media. Record host, OS, controller/driver, drive label, revision, media condition and acquisition settings. Preserve original images and document conversions separately.
